Block Earner is on a mission to bring digital asset infrastructure to everyday Australians, offering trading, loans, and home loans backed by digital assets. To launch the country’s first crypto-backed lending product, the team needed institutional-grade custody from the start: no single point of failure, no insurance gaps, and the ability to scale loan sizes confidently as the business grew. With Fireblocks securing its treasury, Block Earner launched its loan product, grew its offering, and is now expanding into B2B lending infrastructure and international markets.
First to Market: Paving a New Path
Block Earner is the custodian of a client’s Bitcoin ETH, and XRP held as security for their loan. Security of assets is paramount for such a business.
No comparable provider in Australia had built crypto-backed lending before Block Earner, so there was no infrastructure to inherit or adapt. The team needed to find a custody solution that eliminated the vulnerabilities inherent in early-stage digital asset operations: single-key exposure, operational key mismanagement, and the absence of institutional-grade insurance coverage. Without solving the security problem, there was no loan product or business continuity plan.
How Block Earner Built on Fireblocks
Block Earner deployed Fireblocks as the foundation for its treasury and customer fund management, using multi-party computation (MPC) wallets to eliminate single points of failure across all digital asset operations. Customer collateral held against loans is secured within Fireblocks, ensuring no single key or individual can access funds unilaterally.
The integration extended beyond custody. That technical depth gave the team the ability to build and scale complex financial products without standing up separate infrastructure for each capability. The operational result was structural. Instead of dedicating engineering and operational capacity to security monitoring, Block Earner could focus on what it actually does well, which is building credit products that bridge traditional and onchain finance.
Zero Incidents, Larger Loans, and a New Business Model
Since deploying Fireblocks, Block Earner has operated without a security incident. Customer assets have remained safe as loan volumes have grown and the product has matured. The security foundation has also enabled scale in ways that go beyond protection. Block Earner can now support larger individual loan sizes with confidence, knowing the underlying custody is supported.
The team recently launched its partner model, a turnkey solution that lets exchanges and platforms offer Block Earner’s lending product to their customers. This is done without building custody or credit infrastructure themselves.
International Expansion with Scalable Custody
With the Australian market established and a B2B lending channel taking shape, the team is focused on expanding the platform to serve a larger addressable market and developing new credit products that sit at the intersection of traditional and decentralized finance.
Fireblocks will support both moves:
New credit product development: This requires the kind of technical integration depth that Fireblocks provides through its API and DeFi access layer.
International expansion: This requires proven, scalable custody that satisfies regulatory and operational scrutiny across jurisdictions.
“Fireblocks gave us the confidence to offer our loan product, knowing our customers’ digital assets would be safe.”
